Thanks for sharing the photos. True, the Beyers are not mentioned
that often. I have some small Beyer electret lavs I used for
recording in loud settings with good results for a couple of years.
The high self-noise rating of the 930's [signal-to-noise ratio of 71
dB or self-noise of ~23 dB(A)] might not make them an ideal
investment for nature recording considering their relatively high
price. Manufacturer's numbers can differ from field results though.
To get an idea of the role of noise performance, you might be able to
to go to a quiet location and listen to the noise difference between
the 930's and the DPA 4017 which are spec'd with 14 dB(A) self-noise.

For wind protection, I'd go with the stand-by material-- fake fur--
long pile on thin backing that one can see through. There's lots of
discussion about sources for the material in the list archive.
